What is an insider threat? Any person who has authorized access to US government resources to include personnel, facilities, information, equipment, networks, or systems AND uses his/her authorized access, wittingly or unwittingly, to do harm to the security of the United States. This threat includes potential espionage, violent acts against the Government or the Nation including terrorism, unauthorized disclosure of national security information, or the loss or degradation of departmental resources or capabilities.

How can you identify an insider threat? There is no foolproof formula for identifying or predicting an insider threat; however, most maligned insiders exhibit risky behavior prior to committing adverse actions in the workplace.  Currently, there are ~130 Potential Risk Indicators (PRI) associated with insider threat.  Not all of these PRIs will be evident in every insider threat and not everyone who exhibits these behaviors is doing something wrong.  PRIs are clues that require critical thinking and analytic reasoning to determine their relatedness to the insider threat problem set.  A list of insider threat potential risk indicators can be found here.

1. If there are signs that an insider threat incident is imminent, a crime has already occurred, or if you have dire concerns for your safety or the safety of others, contact law enforcement immediately.

2. For non-imminent threats notify your Chain of Command, Command Security Manager, or designated Insider Threat Liaison.

3. Personnel working in an independent duty status can obtain assistance through the nearest available Security Manager, Contracting Officer Representative, or Facility Security Officer.

4. In situations where none of the options listed above are available or you don’t feel comfortable with utilizing them, assistance may be obtained directly from the MCCInTP by sending an email to: insiderthreat@usmc.mil
